INFLATER FOR PNEUMATIC TIRES.

SPECIFICATION formingpart of Letters Patent No. 591 ,841, dated October19, 1897.

Application filed Janu 6, 1897. Serial No. 618,200. (No model.) Patentedin England December 10, 1896,11'0. 28,239.

To all whom it may concern:

Be it known that I, CHARLES GEORGE I'IEAVEN, jeweler, a subject of theQueen of Great Britain, of 107 Vyse Street, Birmingham, England, haveinvented certain new and useful Improvements in Inflaters for InflatingPneumatic Tires and Like Purposes, (for which I have obtained LettersPatent in England dated December 10, 1896, No. 28,239,) of which thefollowing is a specification.

My invention has for its object improvements in inflaters for inflatingpneumatic tires and like purposes by which I can more easily andexpeditiously operate the same.

In order that my invention may be clearly understood and more easilycarried into practical effect, Ihave appended hereunto a sheet ofdrawings upon which I have illustrated examples of the same.

Figure 1 is an elevation of my inflater in a.

closed position. Fig. 2 is a modification of Fig. 1, showing theplungerD extended or open. Fig. 3 is an elevation of the plunger D.

In carrying my invention into practice I form the outer cylinder A withthe cap a, fixed to the bottom end, and formed out of or attached tothis cap are the supports or legs a a and a which form a steady for theinflater when operating the same, or in stead of these supports I mayhinge two or more pieces a to the bottom for the same purpose, asclearly shown at Fig. 2. The outlet a, into which the valve connectionis screwed, is formed close to the bottom. The plunger or piston rodD ishollow and has two slots d and (1 formed in either side, extendingnearly the bottom. The top ends d of these slots run at right angles tothe parts d and d in opposite directions and are enlarged at the end. Ithen fix the cap (1 on the top of this plunger and insert thecoiledspring S, which is held in position by the cross-pin S, and theusual cap is fixed to the bottom, to which the leather sucker s isattached. This plunger is then placed into the outer cylinder, and thepin 3', which forms a bearing for the coiled spring, passes through twoholes formed in the cap a and through the slots d and (1 as clearlyshown at Fig. 2. When the plunger is forced downward, the pin slides upthe slots and compresses the spring, and the plunger can be held in thisclosed position by slightly turning it when the pin drops into theenlargements at the ends of the slots 61 as shown at Fig. 1.

To operate my inflater, the plunger is first released and the inflaterplaced upon the ground, when the plunger is pressed downward by the footof the operator, and when the pressure is released the action of thespring forces it up again, by which means the tire or other article canbe easily and expeditiously inflated. Instead of actuating the plungerby the foot it may be operated by hand if desired.

Vhat I claim, then, is-

In combination, the cylinder, the piston, the hollow piston-rod havingthe slots therein with rightangular extensions, the spring within thepiston-rod and the pin passing through the slots of the rod and held inthe cylinder to form both a support for the spring and also a means oflocking the piston and rod in closed position by engaging the angularextension of the slot, substantially as described. K

In testimony that I claim the foregoing as my own I aflix my name in thepresence of two Witnesses.

CHARLES GEORGE HEAVEN.
